The Pergola adds just a nice unique touch to this new pool in the Bethesda area of Maryland. Look at the corridor effect that invites your friends to enjoy the new pool. We designed and installed this new pool behind a newly built house near Bethesda. Whenever you build a new home or new pool you want it to be unique and different. This gives just that added touch to make it more enjoyable and unique. The exposed aggregate surface gives your sure footing around wet areras and a nice contrast to the new pool and flagstone walkway.
